1. The problem statement, all variables and given/known data I would like to know how to rewrite sin[x^(1/2)]? I have to do a laplace transform of a certain equation but I need to get it into a more usable form... 2. Relevant equations 3. The attempt at a solution I was thinking of using the binomial theorem but 1/2 is neither a even or odd number so I can't use it?
